Description
Technical field
The present invention relates to a kind of calibrating instrument of measurement instrument, in particular to a kind of height calipers automatic calibrating instrument.
Background technique
Height calipers is also known as height gauge, is the measurer for measuring article surface height and position and accurate scribing line, by its knot
Configuration formula can be divided into vernier height slide calliper rule, band table height calipers and digital display height calipers, they are mainly by pedestal, blade, ruler
The compositions such as frame, scribing line measuring jaw, lock screw, reading plotter.Common height calipers resolution ratio or scale division value be 0.01mm,
0.02mm、0.05mm、0.10mm。
Height calipers is widely used in manufacturing and processing enterprise, is the indispensable work of machining, the inspection of the examination and test of products, scribing line
Tool, the quality of direct relation product whether it accurate, or even the economic benefit of influence enterprise.Metrological service, the Chinese government and
Existing skill used by tripartite's correcting mechanism is examined and determine for the height calipers of calibrating for the first time, subsequent calibrating and in-use inspection
Art foundation is JJG31-2011 height calipers vertification regulation.
The conventional method of calibrating height calipers is to examine and determine height calipers point indicating value mistake for main standard with gauge block group
When poor, the measuring jaw measuring surface of height calipers need to artificially be made to contact and can normally slide with gauge block surface, artificially read height
The indicating value of slide calliper rule, is measured with tool microscope when necessary, and the difference of the reading and gauge block actual size is determined as showing for the point
It is worth error, while should be also measured respectively in the case where ruler frame fastens and unclamps.For height card of the measurement upper limit in 300mm
Ruler should be no less than and be uniformly distributed 3 measurement points, and the height calipers of 300mm is greater than for the measurement upper limit, should be no less than and be uniformly distributed
6 measurement points.
208443282 U of patent CN discloses a kind of height calipers calibrating installation, it includes substrate, the second clamp system
